The tyrosine kinase MET (hepatocyte growth factor receptor) is abnormally activated in a wide range of cancers and is often correlated with a poor prognosis. Precision medicine with positron emission tomog. (PET) can potentially aid in the assessment of tumor biochem. and heterogeneity, which can prompt the selection of the most effective therapeutic regimes. The selective MET inhibitor PF04217903 (1) formed the basis for a bioisosteric replacement to the deoxyfluorinated analog [18F]2, intended as a PET tracer for MET. [18F]2 could be synthesized with a “”hydrous fluoroethylation”” protocol in 6.3 ± 2.6% radiochem. yield and a molar activity of >50 GBq/μmol. In vitro autoradiog. indicated that [18F]2 specifically binds to MET in PC3 tumor tissue, and in vivo biodistribution in mice showed predominantly a hepatobiliary excretion along with a low retention of radiotracer in other organs.
